I just have a quick question. Is there an IC like the l293 but that uses mosfets instead of bjt's?

 

Hello,

Take a look at the following chips:
LMD18245
LMD18200
LMD18200QML
LMD18201

All are from national.

thanks. do you think it's better to buy an ic or to make your own h bridge? viewing it in a price prespective is it cheaper to make one or to buy the ic?
